MACHIINE FOR MAKING nultnine-Aucnohs.

SPECIFICATION forming part of Letters Patent No. 385.140, dated June 26, 1888. Applicaiionfi led February 21, 1888. Serial No. 264,786. (No model.)

To all whom it may concern:

Be it known that I, J soon RUSSELL, a citizen of the United States, and a resident of Brooklyn, Kings county, New York, have in vented an Improved Machine for Making Building-Anchors, of which the follrm'ing is a specification.

My invention relates to a machine for making that class of devices used in building and known as building-anchors, and designed for bracing and strengthening \rullsandtiying them to the floor-timbers. As usually conthe anchor is composed of a flat bar of wroughtiron, one end of which is bent-around and firmly clasps a cross-bar, usually of round iron, at its middle. This latter bar is commonly called the spear. The flat bar is twisted a quarter-way round just back of the spear, and at .itsend opposite to the spear said flat bar has a claw or lip bent on it laterally, giving-it an" L shape at this end.

V The object of my invention is to provide a machine that will by successive operations on the two plain bars or elements of the anchor, without handling, join said elements together, twist the body, make the L-shaped bend, and discharge the anchor complete and ready for My invention will be hereinafter fully de- In the drawings, which serve to illustrate my side elevation of the machine, taken from the feeding side, the side illustrate some of the mechanism. Fig. 2 is a transverse section of the machine, taken on line2 2 in Fig. 1, looking toward the right in the latter figure. Fig. 3 is a similar transverse sectiontaken in the same planeas Fig. 2, but looking in the opposite direction. Fig. 4 is a detached view of the twister. Fig. 5 is a detached viewof the cam device for discharging thefinished anchor, and Fig. 6 is a detached View of the cam for feeding the spears from the hopper into the machine. Fig. 7 is a detached and enlarged view of the closing-die. Fig. 8. is a perspective view of an anchor, the product of the machine.

I will premise the description of my machine anchor at each revolution when the machine will be automatically stopped by a shifter. It will be set in motion again by the operator as soon as he has placed a bar for the next anchor. I have not deemed it necessary to show this automatic stopping device, as such devices are in common use on many machines and it forms no essential part of my machine.

A is the bed of the machine. This bed I have broken away at the left in Fig. 1, as it maybe of any length desired, and the lefthand end will be or may be constructed preof the main shaft,

cisely the same as the right-hand end, seen in this figure.

B is the main shaft, rotatively mounted in bearings'at a a a in brackets on the several frames 0 G G on the bed A. Shaft B drives a. vertical shaft, B, through bevel-gears b. Shaft B drives a horizontal transverse shaft,

B fthrough gears b, and. shaft B drives a longitudinal'horizontal shaft, Bflbeneath the bed, through gears b. Themain shaftBalso drives a cross-shaft, B, mounted in frame 0 through gears b", and a cross-shaft,b mounted in frame 0- through gears b. All the gears b b b b b are, by preference, of the same size, so that all of the various shafts will be driven at the same speed. D is a wheel on the main shaft B, by which or through which power is applied to said shaft. The shafts B? B B B are all distinctively cam-shafts. ShaftBmerely connects the main shaft with the shafts below the bed of the machine.

In the several figures,;v represents the body -of the anchor made by the machine, or the barfrom which it is to be formed, and y represents the spear or cross-bar, usually of round iron. Fig. 1 shows the bar 00 in place in the machine and the work on itpartly completed. Its righthand end,where thespear is v to be attached, is seen resting on a fixed die, 0, on the machine-frame, and its lefthand'end is seen resting on a die or anvil, 0', also sew cured to the machine-frame. The first presserfoot, d, is resting on the bar at the right and holding it firmly down upon die a, and the second presser-foot,i d,iis resting on the bar at the left and holding that end of it down firmly on anvil c. The endbender e, which forms the L-like bend on the end of the bar,is

seen at the left in Fig. 1 at theZcnd of its downstroke and ready to rise, and the plunger-die f, whichforms the primary half of the eye in the end of the bar to receive the spear, is seen at the right in Fig. l at the end of its downstroke, the metal of the bar having been bent down into the semicircular hollow in die 0.

The several vertically-moving parts are secured to sliding plates,and are moved up and down by properly-shaped cams. By reference to Figs 2 and 3 these parts willbe'bestunderstood. The foot d is carried by asliding plate, g, (see Fig. 2,) mounted to-play in guides in frame and it is moved upward by a cam, 71, on shaft B, and downward by a cam, i, on the same shaft. The plunger-dief is carried by a sliding plate, j; also mounted inguides in frame 0, and is moved upward by a cam,

shaft.

hand downward by a cam, Z. These cams also are on shaft B.

Reference to Fig. 3 will make clear the means employed for operating the foot (2' and the bender e. The foot d is carried by asliding plate, m, which plays in guides in the frame 0, and-said foot is moved upward bya cam, 11, on the shaft B and 'downward'by a cam, 0, on said shaft. The bender e is carried by a sliding plate, 1), which playsin guides on frame 0*, and is moved upward by acam, g, on shaft B and downward by a cam, r, on said The several sliding plates will be provided with suitable rollers to bear on the cams. The cums that actuate the two resser-feet, the

plnngcndie', and the bender will have 'the proper forms to impart to same the proper extent of movement up and down and will be set so as to lime these movements properlythat is to say, the two feet d d descend first,

. (after a bar,:r,is placed,) and then the plungerdie and bender descend simultaneously, do their work, and immediately rise. The foot d adjacent to the bender 0, also rises, but the foot d remains in place. The next operation is the placing of the spear 3 in the partiallyformed eye-produced by plunger-dief, and I will now describe the means I employ for effecting this.

-E is a hopper to receive the spears. This hopper may be of sheet metal, set inclined on the machine-bed, and provided at its ends 1 with inturned folds s s, Fig. 2, to form keepers,

and a semi-tubular trough-like receiver, 8, at its lower edge. The spears are introduced at the top sidewise until the hopper is full, the lower spear always resting in the trough s.

This hopper will be kept filled by an attendant. The trough s is aligned with the partlyformed eye in the end of bar :0, which restsiu die 0, and the bottom spear, lying in said trough, is pushed out longitudinally and into place in saideye bya pusher, t, suitably guided in bearings and adapted to play in said trough. This pusher is actuated by a lever, F, fulcru med at u on the side of the bed and coupled at its lower end to a slide-rod,.1' the other end of which bears a stud or roller, w, which engages the groove in a cam, G, on the shaft B.

I This cam and the rodv are shown detached in Fig. 6, in which view the observer sees the cam from the opposite direction to thatffrom which he sees the parts in Fig. 2. When the spear has been pushed into place, the eye in bar as is closed, and-themetal made to embrace the spear by a closing-die, e, on the end of a lever, H, which is fulcrumed in the bed at f, and has a roller in the end of its tailor longer arm that bears on a cam, I, on cross-shaft B".

This cam is so set as to drive the closing-die forwardin a slightly-curved path downward, whereby thehot metal of the bar is caused to tightly embrace the spear. The cam then allows the die to recedej Simultaneously with this closing of the eye around the spear the the body of the anchor is twisted, as seen at a," in Fig. 8. The mechanism thataccomplishes this will now be described with especial reference to Figs. 1, 2, and 4.

' In abracket, J, under the bed A,are mounte in suitable guides, so that they may play vertically, two slides, K and K. These slides are provided at their upper ends with jaws g g respectively, which effect thetw'isting. The twisting is effected as follows: The jaws g 9 stand during the primary operations of the machinein the positionsseen in Fig. 2the former above the bar a: and the latter below it. At the proper moment the jaw g is drawn down and the jaw g pushed upward simultaneously. The .bar a: being in their paths they strike and twist it. Fig. 4 shows the position of the jaws when they-have come in contact during their movement with the opposite faces of the bar. When the jaws come opposite each other, the bar will stand between them and on edge. The slides and jaws now in; stantly return to their first position. The

movement is imparted to each ofthe slides by two cams on shaft B Cam h raises slide K and camp It draws it down. K and cam i draws it down. Cams h and i may be alike, and earns h and 2" may be alike.

These cams bear on laterallyprojecting rollers on their respective slides. Fig. 4- showsthe forms 'of the cams that actuate slide K in their proper relative positions. As soon as the twister has completed its work prcsser-foot d Cam 1" raises slide,

is a cam, L. (Seen detachedin Fig.5.) This cam actuates a lever, M, through the medium ofa roller or stud, j, on the lever, which engages a groove in the cam. crumed at k and its longer arm, Z, stands up normally just behind the anchor in the ma chine. When the cam L actson the lever, the

upper end, Z, of the latter is thrown suddenlyv Lever M is fulforward and it strikes the anchor and pushes or knocks it sidewise from its resting place on the dies. The lever then returns toits normal positign. Inprac'tieeI preferto employ a r lever, L, with two upright arms, Z, at some distance apart, as this applies the blow to two points on the body of the anchor simulta- In order that anchors of different lengths may be made on one machine I prefer to pro- 'vlde means for setting theframe G which carries the end-bender e, the foot d, and their operating'mechanisms at any desired point on' the bed-A, so that it may be set at the proper distance from die a. Toefl'eot this I mount the frame 0 'to slide longitudinally along the bed, preferably along guides in a well-known way to keep it properly aligned, and mounta pinion, m, on the base of said frame, which pinion meshes with'a suitable rack, a, on the bed A. By rotation of this pinion the frame 0 is moved to and fro lengthwise of bed A. When set at the proper point on the bed, the frame 0 is securely clamped fast by bolts and nuts 0, the bolts playing along slots in the bed when the frame is moved. r

In order to keep the bevel-gears b in proper mesh, the gearwheel on main shaft Bis held in place by a key which engages a splinegroove or keyway in both the shaft and wheel,

' and by loosening this key the wheelmay be moved into mesh with its mate on shaft 13, and then again keyed fast.

In order to limit the movement of'the spear y when it is pushed into place by pusher t, I- mount on soine part of frame G a stop, 10,

(seen in Figs. 1 and 2,) which stands in, the,

path of said spear. to this stop. I

The attendant takes the hot bar a: and places it in the machine from the sidthe righthand side as seen in Fig. 2-pla'cing the end that is to receive the spear on thenose of the closing-die e and up against an end stop, g. (Seen in Fig. 1.) The machine isnow set in motion and the con ecutive operations performed as hereinbefore described. I

In order to avoid the danger of seriously damaging the machine in case it is set in mo- Ihe spear is pushed up tion'at the wrong time, or while a spear or other obstacle lies-in the hollow of die 0, I prefer to form a hollow in slide], as seen at rfin Fig. 1,

back of the point where the plunger-die f is attached thereto. This reduces so much the. strength of the'metal to which said plungerdie is attached that said metal will yield and break should said die strike an obstacle fore the machine will be injured.

I have herein referred to the feet, die, and bender as attached to their respective sliding plates, in order to avoid prolixity. In fact, they will usually be attached indirectly to said plates through intermediate pieces. This will be understood by .any one skilled in the art. In some anchors the'L-shaped bend is not re? quired, in which case the bender 0 will of course not be employed.

Having thus described my invention, I
